  abstract     = {{Cobalt spinel (Co3O4) catalysts are widely studied in scope of the electrocatalytic oxygen evolution reaction (OER), yet the role of interfacial structural transformation under anodic bias remains under debate. Here, we employ an operando approach, combining a fast electrochemical quartz crystal microbalance with dissipation monitoring (EQCM-D), electrochemical impedance spectroscopy (EIS), and Raman spectroscopy to investigate interfacial transformations of Co3O4 nanoparticle electrodes in alkaline electrolyte. We identify two distinct regimes during the anodic sweep prior to the macroscopic OER onset. At lower potentials, the catalyst interface remains mechanically rigid while reversibly associating several OH−/H2O species per oxidized cobalt site. At higher potentials, pronounced softening of the interface occurs alongside further uptake of electrolyte species. This indicates amorphization and a ‘swelling process’ beyond simple adsorption. Notably, an electrochemical conditioning treatment can suppress mass and compliance hysteresis without affecting OER activity, suggesting that most incorporated electrolyte species do not participate in the OER. EIS further reveals that OER intermediates form well below the apparent OER onset potential. These results advance our mechanistic understanding of interfacial transformations in cobalt-based OER catalysts and establish EQCM-D as a sensitive operando technique for probing electrocatalyst transformations.}},

  abstract     = {{The theory of Total Function NP (TFNP) and its subclasses says that, even if
one is promised an efficiently verifiable proof exists for a problem, finding
this proof can be intractable. Despite the success of the theory at showing
intractability of problems such as computing Brouwer fixed points and Nash
equilibria, subclasses of TFNP remain arguably few and far between. In this
work, we define two new subclasses of TFNP borne of the study of complex
polynomial systems: Multi-homogeneous Systems (MHS) and Sparse Fundamental
Theorem of Algebra (SFTA). The first of these is based on B\'ezout's theorem
from algebraic geometry, marking the first TFNP subclass based on an algebraic
geometric principle. At the heart of our study is the computational problem
known as Quantum SAT (QSAT) with a System of Distinct Representatives (SDR),
first studied by [Laumann, L\"auchli, Moessner, Scardicchio, and Sondhi 2010].
Among other results, we show that QSAT with SDR is MHS-complete, thus giving
not only the first link between quantum complexity theory and TFNP, but also
the first TFNP problem whose classical variant (SAT with SDR) is easy but whose
quantum variant is hard. We also show how to embed the roots of a sparse,
high-degree, univariate polynomial into QSAT with SDR, obtaining that SFTA is
contained in a zero-error version of MHS. We conjecture this construction also
works in the low-error setting, which would imply SFTA is contained in MHS.}},

@article{63720,
  abstract     = {{The aging behavior of closed-cell polyurethane (PUR) foam, a material widely used in household refrigeration, is studied by examining the variation of cell gas composition and thermal conductivity over time. Aging is primarily driven by gas permeation, wherein the initially present cell gases carbon dioxide and cyclopentane are progressively replaced by nitrogen and oxygen from the ambient, resulting in an increased thermal conductivity and reduced insulation performance. The cell gas composition is measured over 1400 days employing gas chromatography, and the thermal conductivity of the foam is measured over 190 days. Morphological foam characteristics, such as average cell diameter, are determined via scanning electron microscopy and barrier measurements are performed to estimate the effective diffusion coefficient of oxygen. To simulate the aging process, one-dimensional and three-dimensional models are developed for both diffusive mass transfer as well as heat transfer. The present model for the thermal conductivity explicitly accounts for condensation effects, i.e. partial condensation of cyclopentane and carbon dioxide occurring at around 12°C, which significantly influences the insulation behavior of the foam. Sensitivity analyses indicate that an initial cell gas pressure of approximately 0.7 bar yields results that closely coincide with the experimental measurements, where the three-dimensional model demonstrates better accuracy. These measurements and simulations provide valuable insights for evaluating and predicting the long-term degradation of the insulation performance of PUR foams.}},

Drawing on insights  from education, psychosocial support, military chaplaincy, and community-building, it reveals the transformative potential of comparative theology in addressing migration, marginalization, and social fragmentation. The contributions critically examine the ethical depth and practical challenges of integrating religious perspectives into social work, offering valuable insights for theory and praxis in pluralistic societies, while also showing the limits and challenges of theoretical models.
Overall, when critically and contextually applied, impulses from comparative theology offer both conceptual depth and practical tools for ethical, inclusive, and transformative social engagement.

Various machine learning methods like support vector machines, neural networks or reinforcement learning were evaluated for their applicability in the prediction context and compared based on their efficiency and most importantly accuracy. The resulting prediction framework uses decision tree ensemble models combined with certain model knowledge to forecast different control strategies. This method was chosen due to its best performance in various test scenarios. Very high accuracy and fidelity were achieved for standard control methods like fixed-time, time-of-day-based and 'ordinary' traffic-based programs. Only for the more sophisticated model predictive control which was tested lower accuracies were achieved.
For the upcoming GLOSA application the penetration of equipped vehicles was varied for different traffic scenarios and control strategies. Results showcase high potentials for enhancing urban mobility and reducing environmental impact by lower emissions and waiting times. However, it is also clear from the studies presented in this contribution that the coordination of the control strategy with the GLOSA vehicles is of enormous importance.}},

The latter method is an integral part of the Qualitative Comparative Analysis (QCA) approach. It is widely used in the literature, e.g., in the field of International Management. Haake and Schneider (2023) give a rigorous description of the connection between the empirical and game theoretic modeling. To justify that the Banzhaf index is an appropriate tool to measure the influence of a condition, this paper discusses a novel axiomatization of the Banzhaf index that uses axioms that are directly linked to the QCA methodology. As a side result, we demonstrate that in our model the Banzhaf index can be reinterpreted as an average of Shapley-Shubik indices.}},

  abstract     = {{In this contribution, we address the estimation of the frequency-dependent elastic parameters of polymers in the ultrasound range, which is formulated as an inverse problem. This inverse problem is implemented as a nonlinear regression-type optimization problem, in which the simulation signals are fitted to the measurement signals. These signals consist of displacement responses in waveguides, focusing on hollow cylindrical geometries to enhance the simulation efficiency. To accelerate the optimization and reduce the number of model evaluations and wait times, we propose two novel methods. First, we introduce an adaptation of the Levenberg–Marquardt method derived from a geometrical interpretation of the least-squares optimization problem. Second, we introduce an improved objective function based on the autocorrelated envelopes of the measurement and simulation signals. Given that this study primarily relies on simulation data to quantify optimization convergence, we aggregate the expected ranges of realistic material parameters and derive their distributions to ensure the reproducibility of optimizations with proper measurements. We demonstrate the effectiveness of our objective function modification and step adaptation for various materials with isotropic material symmetry by comparing them with the Broyden–Fletcher–Goldfarb–Shanno method. In all cases, our method reduces the total number of model evaluations, thereby shortening the time to identify the material parameters.}},
